This is probably "standard fare" for most owners.....

I used some RV store nylon track and sliders for the curtains. The track was a tolerable brown color and didn't ruin the teak strip overhead too much. It bent easily to the curve of the header.

The admiral tells me that the curtains were "interesting" to cut out in order to take into account this curvature.

We decided to have the portside curtain cover two of the windows and the starboard one cover just the helm window. This way, when open, the larger of the bunched up curtains would not be blocking the view at the helm.
